|When evaluating a loupe, please consider the following:
Quality of the Optics
Quality of the Frame
Depth of Field
Field of View
Flip-Up loupes versus TTL loupes

Quality of Optics The best method to evaluate loupes' optic quality is to look at an object with straight
black lines. The most common signs of poor quality optics are low resolution as shown in figure A,
and image distortion as shown in figure B. When viewing through high quality loupes all lines will
appear straight and clear, as shown in figure C.
Quality of Frame can be determined by look at the material of the frame and tightness of all the
Magnification requirements are determined by the type of tasks you perform while wearing your
loupes. If you are dental hygienist, you might only need a 2.5x magnification loupe system. But if you
perform surgical tasks like root canal procedures, then you need a loupe system of 4.0x magnification
Light Transmission is important not only for quality of the image, but also for the comfort and
safety of your patients. Optimized light transmission means that you can work with less light, reducing
your eyestrain while minimizing the exposure of your patient to bright light.
Depth of Field is defined as the range of distance that is in focus without moving your head. The
ergonomic benefits of a large depth of field are clear because there is less need to move your back,
neck and head to work effectively.
Field of View refers to the amount of the original object that you can see from left to right and top to
bottom. Different applications have different needs. A larger field of view is not always the better choice.
for instance, an endodontist might prefer to see only the small area being treated, whereas a
periodontist would like to see as much of the surrounding area as possible.
Working Distance requirements varies by the user's height and body type, and also by how you
sit or stand while work with your patients. The best method of determining your working distance is to
measure the distance between your eyes and the patient’s teeth, while sitting or standing in an
ergonomic position in your normal workspace.
TTL vs Flip Up
TTL stands for "Through The Lens", It means that the loupes are glued to your lens. Although TTL is
slightly lighter than Flip-Up system, it can not be moved from line of vision and the user can not make
adjustments to the angle of declination to accommodate for the patient's position. And since each pair
of TTL loupes is custom made, it is much more expensive than the Flip-Up loupes.
Comfort of Use is determined by the weight of the whole system and the ergonomic design of the
frame. Our frames are made from titanium, one of the lightest and toughest material used for high end
glasses which will ensure the ultimate comfort for long periods of usage.
